摘要：

A new cation-anionic complex of hypercoordinated tin, {[L2Sn(OH)]+BF4-}(2) (L is a bidentate (2-oxopyrrolidino)methyl C,O-chelating ligand), was obtained by the reaction of L2SnCl2 with AgBF4 and structurally characterized by X-ray diffraction analysis. In crystalline form, the BF4- anions are bound to the dications through O-H...F hydrogen bonds (the H-F distance is 1.78 Angstrom). The octahedral coordination of the Sn atoms is strongly distorted because of a weak additional interaction with solvate molecules of dioxane (the Sn-O distance is 3.16 Angstrom).
